Abstract
Abstract Char waste water, a waste product in sugar refining, derived by water washing spent animal charcoal (char), is useful as a sporulation medium for the production of Bacillus popilliae spores. Bacillus popilliae spores are useful as a microbial insecticide in the control of Japanese beetles since B. popilliae spores cause milky disease in the Japanese beetle and other insects, such as the European chafer.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
27 words
A method of sporulating a microorganism capable of undergoing sporulation which comprises incubating said microorganism in a medium containing filtered cane sugar refinery animal char waste water.
Claim 2
Independent Claim
27 words
A method of sporulating a microorganism capable of undergoing sporulation which comprises incubating said microorganism in a medium containing filtered cane sugar refinery animal char waste water.
Claim 3
Dependent Claim
13 words
A method in accordance with claim 1 wherein said microorganism is Bacillus popilliae.
Claim 4
Dependent Claim
13 words
A method in accordance with claim 1 wherein said microorganism is Bacillus lentimorbus.
Claim 5
Dependent Claim
35 words
A method in accordance with claim 1 wherein said microorganism is Bacillus popilliae and wherein said microorganism is incubated in said medium at a temperature of about 27°C. for a period of about 24 hours.
Claim 6
Dependent Claim
47 words
A method in accordance with claim 4 wherein the resulting produced spores are recovered from the incubation medium by the addition of finely divided talc to the incubation medium and a resulting solids admixture consisting essentially of talc and spores separated and recovered from said incubation medium.
Claim 7
Independent Claim
133 words
A method of producin spores of Bacillus popilliae which comprise effecting vegetative growth of Bacillus popilliae in a growth medium comprising 1.5% by weight yeast extract, 0.3% weight K 2 HPO 4 , 0.2% by weight glucose and 0.5% by weight triptose, the pH of said growth medium having been adjusted to a value in the range about 7.2-7.3, said growth medium having been sterilized before being employed for the vegetative growth of Bacillus popilliae therein, recovering the resulting produced cells of Bacillus popilliae, introducing the recovered cells of Bacillus popilliae into an incubating medium for effecting sporulation of said cells, said incubating medium comprising filtered cane sugar refinery animal char waste water, incubating the cells in said incubating medium to induce sporulation of said cells and recovering the resulting Bacillus popilliae spores.
Claim 8
Independent Claim
133 words
A method of producin spores of Bacillus popilliae which comprise effecting vegetative growth of Bacillus popilliae in a growth medium comprising 1.5% by weight yeast extract, 0.3% weight K 2 HPO 4 , 0.2% by weight glucose and 0.5% by weight triptose, the pH of said growth medium having been adjusted to a value in the range about 7.2-7.3, said growth medium having been sterilized before being employed for the vegetative growth of Bacillus popilliae therein, recovering the resulting produced cells of Bacillus popilliae, introducing the recovered cells of Bacillus popilliae into an incubating medium for effecting sporulation of said cells, said incubating medium comprising filtered cane sugar refinery animal char waste water, incubating the cells in said incubating medium to induce sporulation of said cells and recovering the resulting Bacillus popilliae spores.
